☂️ Umbrella issue for replace deprecated [UIScreen mainScreen] in iOS 16 #125496
Description
One instance was introduced in flutter/engine#41460
Use Case
UIScreen mainScreen is deprecated in iOS 16 per https://developer.apple.com/documentation/uikit/uiscreen/deprecated_symbols. We should use the recommended replacement UiWindowScene which was added in iOS 13 to support multiple windows and provide a fallback for iOS 11 & 12.
Proposal
There are several places where the deprecated UIScreen mainScreen is used and should be replaced:
| File Name | Tracking Issue |
|---|---|
FlutterViewController.mm & FlutterViewControllerTest.mm |
|
FlutterPlatformViews_Internal.mm |
|
FlutterDartProject.mm & FlutterDartProjectTest.mm |
|
FlutterView.mm |
|
vsync_waiter_ios.mm |
|
SemanticsObject.mm |
|
FlutterPlatformViews.mm & FlutterPlatformViewsTest.mm |
|
AppDelegate.m |
Out of Scope
Currently, most Flutter behavior is built and tested for the single window. The simple replacement proposed in this issue may not address all multi-window scenario cases.
